The empanada is a food I never really encountered before moving to New York. I haven't been to many empanada places, but I have gone to a local place many times. From my experience, empanadas can range from fairly large (3 would be a meal), to about half that size. Outside the Queen's Center Mall is an excellent empanada place, which has a small sized empanada, Mama's Empanadas.
Their menu is fairly large, with about 20 different types of empanadas, along with other miscellaneous items. They have two types of empanadas, flour ones, and corn ones. They both are good, but I prefer the corn ones, which have a great bite which is both firm, crunchy, and tasty. The insides of the empanadas usually works well, except the spinach & cheese, which I thought was too watery.
Overall, I recommend this place highly. The best empanadas I've had so far, although my experience is too limited for that claim to mean much. By the way, this place is takeout only.
